At Cloudline, we make merino wool socks and base layers to inspire you to get outside. Made in the USA, our comfortable and durable products are backed by a lifetime guarantee.

For hikers, runners, ultralight travelers, and the casual outdoor enthusiast, Cloudline Apparel makes merino wool socks and base layers to stand up to all of life’s adventures. Made in the USA, our products are backed with a Lifetime Guarantee — meaning you can trust that your gear will work as hard and as long as you do.

We’ve all had that nagging feeling — miles into a hike, or several runs into your day on the slopes — where something just doesn’t feel right. A bunched toe, a slouched sock, a rubbing seam: the tiny distractions that get on our nerves. 

With Cloudline socks and base layers, you can enjoy your adventures without those annoyances. Because what you wear shouldn’t slow you down — it should support you all the way to the Cloudline.

As an outdoor adventurer, you need your gear to work as hard as you do. 

The glory of summiting a mountain peak shouldn’t be shadowed by a week of hobbling on blistered feet. Feel as inspired on your final mile as you did on your first with Cloudline moisture-wicking merino wool. Stay dry, cool, and comfortable on the most epic of adventures.

Cloudline socks are knit exclusively with premium merino wool certified by the Responsible Wool Standard. This ensures our wool comes from farms that take a responsible approach to land management, and follow the principles of the Five Freedoms for farm animals.
